QB and bank continuous errors

 Try opening your QBO account on any private/incognito browser. Did you enccounter the same problem?

Allow me to assist you in addressing and resolving the bank error you’re experiencing, Waterhousepumps.

To get started, could you please provide the specific error message you've encountered and the name of your bank? Having these details will enable us to understand the issue and determine the most effective solution for you.

In the meantime, I recommend verifying whether your bank is undergoing any scheduled maintenance that might affect connectivity. You can confirm this by visiting your bank's official website to check for notifications or alerts about maintenance activities. 

If you’ve verified that there are no issues on your bank’s end, I recommend clearing your browser’s cache and cookies, as suggested by @SIAB  in this thread. Outdated or corrupted files in your browser can sometimes cause errors when connecting to your bank in QBO.
